CYLINDER FULL KIT 102MM YAMAHA YZ 450 10-20, ATHINA S4F102000040 500CC BIG BORE, (Piston included)

Athena 102mm Big Bore Cylinder Kit for Yamaha YZ 450

Upgrade your Yamaha YZ 450's performance with this complete Big Bore Cylinder Kit from Athena. Designed for enthusiasts seeking enhanced power and reliability, this kit features a forged racing piston engineered in Italy for superior strength and durability.

Athena pistons are crafted from a high-performance aluminum alloy with a high silicon content, ensuring exceptional resistance and excellent performance comparable to or exceeding Original Equipment (OE) standards. The cutting-edge CNC machining guarantees precise dimensional tolerances, while the perfectly smooth profile promotes optimal airflow and flame propagation.

For reduced friction and increased longevity, some pistons feature a molybdenum disulfide coating applied via screen printing. The included piston rings, produced in Japan with wear-resistant coatings (PVD or chromium nitride), further minimize friction and maximize durability. These rings adapt seamlessly to the cylinder liner even under low tangential load.

This comprehensive kit includes the piston, pin, circlips, and piston rings, all of which are replaceable and interchangeable. Athena products with increased displacement and power beyond road regulations are intended exclusively for competitive use.
